VIES – Verification and automation in cross-border e-commerce trade

cross-border e-commerce

The development of e-commerce opens new opportunities for small and medium-sized enterprises, particularly in the area of international (cross-border) sales. Thanks to the reach provided by the Internet, companies can easily reach customers in different countries, contributing to revenue growth and global expansion.

In light of the dynamic development of cross-border trade in Europe, where 70% of internet users already shop online [1], and one-third of them buy from other EU countries, the security and efficiency of international transactions become crucial. Particularly important is the proper verification of contractors in the VIES (VAT Information Exchange System).

However, entering foreign markets requires careful planning, including thorough verification of contractors to avoid financial and tax risks.

Verification of foreign contractors – why is it important?

Verification of contractors, especially regarding VAT, is crucial in international business. The European Union has introduced the VIES system, which allows checking whether a given business entity is registered as a VAT payer in another EU member state.

This enables entrepreneurs to:

  • Ensure contractor credibility – lack of registration in the system may indicate that the company is not conducting legal business activities.
  • Avoid errors in tax documentation – correct VAT identification is necessary for applying zero VAT rate in intra-Community transactions.
  • Minimize the risk of tax fraud – VIES helps identify potential abuses, such as fictitious companies.

How to use the VIES system?

The VIES system is available online and is free. To verify a contractor, you need to:
1. Visit the official VIES website and fill in the mandatory fields:
2. Select the contractor’s country.
3. Enter their VAT number.
4. Receive confirmation of registration or information about lack of entry.

In case of no entry, it’s worth contacting the contractor directly or the tax office in the given country to clarify the situation.

If you have a problem with your or your contractor’s incorrect EU number, we encourage you to read the article on our blog: VIES – invalid EU VAT number during verification.

Benefits of automation and integration of VIES verification with business processes

Automation of the VAT verification process can significantly improve company operations, particularly in e-commerce. Solutions available on the market integrate accounting and sales systems with VIES, allowing for:

  • Automatic verification of contractors when placing orders.
